Hope it may help .
Have you the "Twelve Days in May" book ?
Pages 15 to 56 covers the day .
Of interest on page 17 is the details of 600 Sqn's six Blenheim attack to Waalhaven. Their fate and return of one crew on a Destroyer with the Dutch Royal Family. Of the other crews only one pilot from one a/c and an observer of another a/c survived.
